Application filed September a, 1917. Serial No. 191,263.

To all whom/it may concern:

Be 1t known that we, NATHANIEL LEA and GEORGE WYLLS LEA, both citizensflof the Dominion of Canada, residing at 208 :1? Alberta Corner, in the city 0t Calgary, in the Province of Alberta, Dominion of Canada, have invented new and useful Improvements .in Adjustable Automobile-Bearings, of which the following is a specification.

Our invention relates 'mprovements in adjustable bearings for steering knuckles on automobile axleaand the primaryobject is to provide a hearing which may be adjusted and oiled with facility and which will hold the supported which ordinarily is incident where a spindle bolt and bushings are used.

These objects are attained by the mechanism illustrated in the accompanying drawings in which similar figures refer to similar parts throughout the several views and in which:

Figure 1 is a side elevation of a portion of an automobile axle with bearings con structed in accordance with this invention:

Fig. 2 is a portion of the movable part of such an axle (the bearings nht shown),

Fig. 3 is a vertical cross-sectional view of a portion of said axle showing the bearings constructed in accordance with this invention, and

Fig. 4 the movable part of in id bearings.

iiei erring more particularly to the drawings 1 is one end of the stationary portion of an automobile axle.

9 is an externally threaded be aring set in an internally threaded perfora ion in the lower arm of the axle 1.

8 is an externally threaded dust collar set in the said internally threaded perforation in the lower arm of the axle 1.

2 is an externally threaded bearing set in an internally threaded perforation in the upper arm of the axle 1. g

4 is an externally threaded dust collar set is a vertical cross-sectional view of said axle which is held in the said internally threaded perforation.

in the upper arm-of the axle 1.

3 is a jam-nut internally threaded, and mounted on the bearing 2.

V 7 parts nrmly in position.- lhe mechanism use eliminates all wear 'to hold the bearing 2 in place.

10 is a portion of an automobile axle'upon which an automobilewheel (not shown) is mounted for rotation and having the vertical r arms 5-5 mounted in the bearings 9 and 2 for partial rotation. I

The assembling of the mechanism is as follower- The dust collars land 8 are slipped over opposite arms 5-5 which arms are then inserted in opposite perforations in the axle 1.

The bearing 9 is then turned into the perforation in the lower arm of the axle 1 until tightened. The bearing 2 is then turned into the perforation in the upper arm of the axle 1 until the axle 10 is held firmly but allowed to rotate. The jam-nut 3 is then tightened The dust collars l and 8 are then turned into the perforations as shown in Figs. 1 and? The bearing 2 may be tightened or loosened as required from time to time.

\Vhile in this specification and in these drawings we have shown our invention to gether with certain features of construction and applied to a particular form of automobile axle, it is our intention that this application should coversuch variations as may be necessary to suit practical conditions, so long as the same are contemplated in what is claimed.

We claim in bearings for automobile axles andin combination of two cup-shaped bearings threaded into opposite arms of an automobile axle, a spindle-shaped member having arms with convex ends each fitting into one of said cup-shaped bearings, dust collars on said arms of the spindle-shaped member threaded into said arms of the automobile axle-a jam-nut on the upper of said cupshaped bearings.

Signed at the city of Calgary, in the Province of Alberta, this 22nd day of August, A. D. 1917.
